Solve for m16 - 18m = -19m

1 answer:

3 0

You want to get m by itself and the easiest way to do that is to add 18 to both sides, so you’re left with 16=-1m. Then you divide 16 and -1m, and your answer should be m=-16

I need help with this question

egoroff_w [7]

Answer:

V= 432mm^3

Step-by-step explanation:

volume of a rectangular prism is width times length times height.

or V= w x l x h

so the volume is all three numbers multiplied together. This gets 432.

the units are mms, and we are finding the volume of a 3 dimensional object. so it is always going to be raised to the power of three.

Prove that if an integer is a perfect square and a perfect cube, simultaneously, then it is either of the form 7k or 7k+1

Bogdan [553]

If an integer is both a square and a cube, it can be of the form:
(a3)^2
Now,
since a cube can be of the form 7k or 7k+-1(thanks to FoolForMath),
we write
a^3=7k
and get the no to be
49k^2
, which is in the form of 7 times something
49k^2=7×(7k^2)
Now put
a^3=7k+−1 Square it
and you'll get a number in the form of (7times something +1)

Arthur is organising his collection of DVDs .He has 36 altogether. The ratio of comedy films to action to horror is 4:8: 1 How m

sweet-ann [11.9K]

Answer: Because of the total number of DVDs given (36)the number of individual type of DVD are coming in decimals such that

Number of comedy films =11.07

Number of Action films =22.15

and Number of horror films =2.78

I also solved using total number of DVDs as 26 and the results were as follows

Number of comedy films =8

Number of acton films =16

and Number of horror films =2

Step-by-step explanation:

Total number of DVD collection = 36

ratio of the type of DVD =comedy films to action to horror = 4:8: 1

Total ratio =4+8+1 = 13

Number of comedy films = ratio of comedy films/ total ratio x Total DVD collection

= 4/13 x 36= 11,.07 rounded to 11 comedy films

Number of action films = ratio of action films/ total ratio x Total DVD collection

= 8/13 x 36= 22.15 rounded to 22 action films

Number of horror films = ratio of horror films/ total ratio x Total DVD collection

1/13 x 36=2.78 rounded t0 3 Horror movies .

The numbers of each DVD are giving decimal numbers .

Using

Total number of DVD collection as 26.

we have that

Number of comedy films= 4/13 x 26 = 8

Number of action films= 8/13 x 26= 16

Number of Horror films = 1/13 x 26 = 2

Which rule describes the x-coordinates in the translation below?.

Ivenika [448]

Answer:

A) x + 0

Step-by-step explanation:

In triangle ABC, the coordinates are: A(1, -1), B(1, -5) and C(4, -5)

In triangle A'B'C', the coordinates are: A(1, -5), B(1, 1) and C(4, 1)

Look at the x-coordinates in both the triangles remains the same because the triangles are reflected over x-axis, therefore, only the y-coordinate changes.

Therefore, the rule for x-coordinates = x + 0

Answer: A) x + 0

Hope this will helpful.

Thank you.
